No. 15/472,621, filed on Mar. 29, 2017, which claims priority under 35 U.S.C. § 119(a) to Application No. 16162760.9, filed in Europe on Mar. 30, 2016, all of which are hereby expressly incorporated by reference into the present application.

FIELD

The present disclosure relates to a monitoring system, which is configured to monitor the status and/or performance of one or more hearing devices in an environment. More particularly, the disclosure relates to a system for monitoring health related parameters, wherein the monitored parameters are accessible from a central unit and/or from a cloud service.

BACKGROUND

The increasing focus on health care monitoring and the general perception of having a good life quality in view of the increasing average age amongst humans creates a series of different demands to the health care systems that at least to a degree assists elderly people in maintaining a good quality of life.

With the expansion and developments of the internet and telecommunication possibilities throughout the years the health care system has, started taking advantage of these communications means in order to develop monitoring systems, which may aid a human in obtaining a good quality of life by self-monitoring. Such monitoring systems have been known to e.g. be implemented in auxiliary devices, such as mobile phones, where apps have been developed to monitor different health and performance parameters of a person.

In care taking facilities, usually a series of elderly people are living together and are to a degree dependent on the assistant of caretaking personal for gaining a good quality of life. The caretaking personal are often pressed on time in view of the amount of patients (i.e. elderly people) living in the facility compared to the amount of personnel and resources of the facility. Accordingly, in order to assist the caretaking personal in resource and time optimization, the caretaking personal may benefit from any information that may be collected directly and automatically from the elderly people living in the facility. Furthermore, many elderly people wear health assistant devices, such as hearing aids, which requires maintenance, in the form of battery change, cleaning, dome changing etc. The elderly people wearing e.g. hearing devices often have various levels of mobility, motor skills, mental capabilities and technical awareness. The understanding of e.g. batteries and their limitation, the need of changing them and the ability to do so is not a given capability of all users. Accordingly, the basic maintenance of the instruments and accessories are in caretaking facilities, such as institutions, care centres, old people's homes or hospitals, often the responsibility of caretaking personnel.

In view of the increasing demands on the health care system, and especially the caretaking personal employed in caretaking institutions, there exist a need for a sufficient and high quality monitoring system which allows for a continuously monitoring of residents of e.g. a caretaking facility as well as monitoring of their health assisting devices.

At least an object is to have a desirable, high quality alternative way to ensure the maintenance of auxiliary devices such as hearing devices, while providing for a monitoring of e.g. health parameters of elderly people in a caretaking facility. The present disclosure provides at least a series of suggestions and alternatives on how to monitor one or more hearing aids in an environment, so as to ease the maintenance and monitoring of hearing aid parameters worn by different users in a large environment, where the demand on resources on e.g. the caretaking personal is high.

SUMMARY

According to the disclosure, a monitoring system for monitoring parameters of one or more hearing devices, is provided for. The system comprises one or more hearing devices having one or more sensors configured to perform measurements from said hearing device, and a memory configured to store a set of measurement parameters based on the measurements measured by the sensors. The memory is furthermore configured to store a set of performance parameters of the hearing device. In this way, the hearing device is configured to measure a set of health measurements by use of sensors and to store parameters related to the performance, such as battery status, feedback status, dome position and so forth of the hearing device.

The hearing device is furthermore configured to transmit the stored performance and/or measurement parameter through a wireless signal, wherein the monitoring furthermore comprises a number of access points configured to receive the transmitted stored performance and/or measurement parameters through said wireless signal wherein the number of access points furthermore are configured to transmit the received performance and/or measurement parameters to a central unit, which central unit is configured to communicate with an Internet and/or a cloud service, which enables the measured performance and/or measurement parameters to be shared between a facility having the access points and the central unit and a remotely located facility, such as e.g. a hospital and/or an health clinic.

The central unit according to the monitoring system comprises a processing unit having a set of stored normal values representing each of the one or more measurements and/or performance parameters, and the processing unit is configured to evaluate the received performance and/or measurement parameters against the set of stored normal values in to detect a deviation from the normal value, wherein when a deviation is detected, the processing unit triggers the central unit to prompt an alarm to a user of the monitoring system and/or to transmit a notification signal directly to the hearing device.

With such a monitoring system as defined herein, the caretaking personnel of a health care institution, such as hospitals, elderly home, nursery etc. is able to monitor a series of measured performance and/or sensor measurement parameters collected by a number of hearing device, without having to physically monitor the user of the hearing devices before it is relevant. In this way, the control unit collects measurements and enables the caretaking personal to optimize time and resources in view of maintenances, health monitoring etc. used for assisting humans in gaining a better life quality. That is, the monitoring system informs the caretaking personnel about deviations arising in a hearing device users measurements allowing the personnel to take action when it is relevant. In this way, unnecessary actions are avoided, while at the same time, the necessary actions for assisting the elderly people during the needed times are enabled through this system.

With the control unit receiving, storing and evaluating the one or more measured performance and/or measurement parameters by communication with a series of access points in a facility, changes in e.g. measured health related issues (i.e. measured by the sensors) and/or performance changes of e.g. a hearing device may be monitored for each person wearing a hearing device in the facility at one unit.

Furthermore, with the monitoring system it is possible to provide a system by which it is possible to ensure that the maintenance of hearing devices and their accessories is carried out as scheduled. That is, the status and/or different parameters, for example measured by one or more hearing devices, are communicated to a series of access points of the system. The access points communicatively transmit data of the current status of the hearing device to at least a central unit and/or a cloud based solution, whereby the status may be monitored, checked and/or changed by for example a hearing care professional or any other health care professional, which has access to the data.

This could for example be the caring professionals in an elderly home, which with the system according to the disclosure, would be able to monitor, check and/or change the behaviour of the elderly resident hearing aids, or monitor the health parameters measured by the hearing aid.

The performance and/or measurement parameters of one or more hearing devices may include any desirable parameter including the status and/or performance of one or more parameters that can be measured by the hearing devices. Accordingly, such parameters may include measurements made by the hearing device(s) by means of one or more sensors. The one or more sensors may be arranged at least in connection with the hearing devices, such as for example being an integrated part of the hearing device and/or being in communication with one or more sensors placed on a body part of a user.

Such sensors could for example include electrodes, health sensors, skin sensors, accelerometers, antennas or any other kind of suitable sensors for monitoring different health parameters of a person.

The monitoring system comprises a number of access points configured to receive wireless signals transmitted by the hearing devices. The access points may be located in any suitable location in an environment in which a hearing aid user is situated. The access points may be provided as permanent installations in e.g. a health care institution as previously described.

The access points may preferably be connected to a central unit communicatively connected to the Internet/cloud. This may be achieved by means of wireless and/or wired connections. In this way, the data received by the access points may be stored in a cloud solution and/or on the internet, such that a remote access to the data may be achieved. This provides for the possibility of having a remote monitoring of the hearing device, such that for example a doctor or other hearing care professional is able to gain access to the data sent by the hearing devices. The data sent by the hearing device would thus lead to the possibility of a remote health monitoring of the person wearing the hearing device, and thereby aiding a care professional in diagnosing and controlling potential treatment of the hearing device wearer.

Access points may, due to their small size, be placed in public transportation, at strategic locations in the public domain including cultural venues, shopping malls, sport facilities, community centres and religious sites. Accordingly, the system according to the disclosure can provide a service in which hearing care professionals can help their customers remotely while the hearing device users are at home or moving about on their own. The access point may similarly be placed in a nursing home, whereby the care professional of the nursing home would be able to monitor the health status and/or the status of the different hearing devices through the central unit, which receives data from each of the hearing devices worn by a resident of the nursing home.

In an embodiment, the transmitted performance and/or measurement parameters are communicated to the central unit through at least two access points. That is, the data (i.e. the performance and/or measurement parameters) is transferred through at least two access points prior to reaching the central unit. In this way, the access points forms a mesh network, which makes the infrastructure highly scalable, because not all access points are required to be physically connected directly to the network master (i.e. the central unit). Instead, access points can connect directly with other access points within their range, and relay any message, information, status, measured parameters etc. to other access points so that it eventually is delivered from the hearing device to the network master, such as the central unit. In addition, the hearing devices themselves may be applied as access points, and relay information from another hearing instrument to a dedicated access point if it is without connection to a dedicated access point itself. In this way the data transfer is reliably secured, such that if any access points in the mesh is not available, the data may still be transferred in a secure and reliable manner to the central unit, thereby maintaining the monitoring flow to the caretaking personnel.

The monitoring system is configured to automatically monitor measured and/or performance parameters of the one or more hearing devices received by access points and transferred to the central unit.

When transmitted to the central unit, the performance and/or measurement parameters comprises an identification parameter, wherein the central unit is configured to receive the identification parameter and correlate the received identification parameter with a set of identification parameters stored in the central unit, so as to identify the hearing device of said transmitted parameters. In this way, an identification parameter belonging to a resident of the health care facility may be used to store the measured parameters, such as health related parameters to the correct resident. That is, the central unit may contain a database with identification parameters belonging to each of the residence, whereby the central unit is configured to store the incoming measurements from the hearing devices to the correct residents. In this way the central unit automatically stores the data transmitted trough the access point from the hearing devices.

The monitored parameters are accessible from the central unit and/or from a cloud service by means of any suitable communication connection and communication devices. That is, the monitored data could be accessed through a computer, a phone, such as an iphone, an app or any other suitable device at the health care institution and/or remotely from there.

Furthermore, in an embodiment, the number of access points is configured to request a status from one or more hearing devices upon instructions transmitted from said central unit and/or in a continuous, e.g. scheduled manner.

In this way it is ensured that the monitoring system continuously request data from the hearing devices of residents in the facility, whereby it is ensured that the caretaking personnel may always follow the status and any change to the parameters, which they should be aware of. Within the meaning of scheduled manner, should be understood, that the access point maybe be configured to request a status in accordance with a given schedule, such as e.g. 3 times a day at certain times, etc.

In a further embodiment, the hearing devices may continuously transmit performance and/or measurement parameters to said access points, wherein said access point is configured to store said performance and/or measurement parameter, such that upon request from said central unit, said performance and/or measurement parameters are transmitted to said central unit.

In this way, the central unit may store the parameters upon request, for example, when instructed by a caretaking personnel or in schedule manner as previously described.

According to the disclosure, the monitoring system is configured as a service platform configured to be installed in a care center environment, such as in a nursery, care centers and/or old people home, where the performance and/or measurement parameters may be monitored for several hearing devices at the same time through the central unit in a structured manner. This makes it possible to reduce the resources needed to plan, control and execute an appropriate level of service and maintenance. The service platform may be based on any suitable communication technology, including “Bluetooth low energy” and hearing devices configured to communicate by using “Bluetooth low energy”

Accordingly, in an embodiment, the monitoring system may be configured such that the control unit upon a detected deviation in the transmitted one or more parameters of the one or more hearing device is configured to automatically notify an external device, preferably an external device of service personnel and/or a health professional.

It should be noted that in a preferred embodiment, the number of access points are configured as a plurality of communication devices comprising a battery electrically connected to a printed circuit board having an integrated transmitter unit comprising a radio unit or an antenna for transmission of wireless radio signals, and wherein the plurality of communication devices are installed in e.g. a nursery, care centers and/old people's home.

The one or more access points may comprise a memory for storing the transmitted performance and/or measurement parameters, until a request from the central unit is received.

As already implied the monitoring system is thus configured to monitor a series of different parameters of a hearing device. That is, the monitoring system may be configured to monitor one or more measurement parameters transmitted by the one or more hearing devices and including stored measurements of one or more of: a blood sugar value, a heart rate, a temperature, an acceleration, a vibration, a blood pressure, a skin conductance, an ultraviolet light exposure, a pH level, a bacteria level, a humidity and/or an electrical activity of the brain of the hearing device user(s), wherein the performance parameters may include one or more of a registration of: a battery status of the hearing devices and/or a surroundings and/or a positioning.

Accordingly, a series of different applications of the system exists, which will be explained in more detail in relation to the figures.

An example with regards to the performance parameters of the hearing devices includes that the system according to the disclosure may be configured to monitor the battery level remotely and report low power level to the service provider, such as a nurse, care personnel, a hearing care professional, a doctor, etc. Accordingly, battery change/replacement can be carried out in a scheduled manner by the service provider so that less hearing device ‘downtime’ is experienced.

By applying a system according to the disclosure, it is possible to extend the battery lifetime by remotely controlling the power scheduling.

By applying a system according to the disclosure, it is also possible to reduce the risk of injury for hearing device users with dementia due to the system's capability of detecting hearing devices leaving a building.

Location-based or situation-based hearing device program choices can be pushed to the hearing device(s). Hereby, by applying a system according to the disclosure, it is possible to give relevant information related to locations or situations to the hearing device users. It is possible to select any desired location, including locations as a TV lounge, a diner room, a movie theatre and relate such location to a predefined information and/or program role.

From the caretaker's/service provider's perspective, the system according to the disclosure solves several problems/challenges:

-   -   The system makes it possible to shift from status polling of         several hearing device users to a centralised, pushed status         from the service platform.     -   The system makes it possible to gather knowledge of battery         level in all hearing devices of the system.     -   The system makes it possible to report hearing device status of         all hearing devices of the system to the service provider.     -   The system makes it possible to shift from user interrupt based         service to proactively planned and executed service.     -   The system makes it possible to detect the location of the         hearing devices and thus the location of the users wearing the         hearing devices. This is a valuable tool in situations where         users (e.g. with dementia) get “lost”.     -   The system makes it possible to broadcast voice messages or         other types of notifications to the hearing device users when         needed.

In some hearing devices, the output unit may include one or more output electrodes for providing the electric signals such as in a Cochlear Implant.

It should be noted that any type of hearing aid type, comprising at least some of the above-mentioned features may be used in connection with the system according to this disclosure.

Now referring to FIG. 1, which illustrates a schematic view of a monitoring system 2 according to the disclosure, it can be seen that the monitoring system 2 (also referred to as the system) comprises a plurality of access points 4, 4′, 4″, 4′″, 4″″ provided in different locations 6, 6′, 6″, 6′″ in a building.

The building comprises a dining room (provided with tables and chairs) indicated as a first location 6. Several access points 4 are provided in the first location (dining room) 6. The building moreover comprises a TV room indicated as a second location 6′. A plurality of access points 4″″ are provided in the second location 6′. The building additionally comprises a first residential area indicated as a third location 6″, a second residential area indicated as a fourth location 6′″ and a third residential area indicated as a fifth location 6″″. A plurality of access points 4′, 4″, 4′″ are provided in the first residential area 6″, the second residential area 6′″ and the third residential area 6″″, respectively.

The building may be any type of building including an institution, a care center, an old people's home or a hospital.

The access points 4, 4′, 4″, 4′″, 4″″ is preferably a wireless personal area network based on for example bluetooth, such as Bluetooth low energy (Bluetooth Smart) technology. The access points 4, 4′, 4″, 4′″, 4″″ are configured to communicate wirelessly with one or more hearing devices, such as hearing aids. Hereby, the hearing aids of one or more hearing aid users may receive information from the access points 4, 4′, 4″, 4′″, 4″″ and transmit data which is received by the access points 4, 4′, 4″, 4′″, 4″″.

The system is suitable for use in connection with hearing aid users in public as well as private buildings. The system is suitable for being installed in buildings with multiple hearing device users. The data that is collected by means of the access points 4, 4′, 4″, 4′″, 4″″ may be reached by remote individuals including hearing care professionals outside the building. Also it is possibly that the data is stored in a central unit at the location of installation of the access points.

The access points may be provided as small sized communication devices comprising a battery electrically connected to a printed circuit board having an integrated transmitter unit comprising a radio unit and an antenna for transmission of wireless radio signals. Due to their small size, the access points 4, 4′, 4″, 4′″, 4″″ may be placed in public transportation, at various locations in the public domain e.g. in cultural venues, shopping malls, sport facilities, community centers, religious sites.

The plurality of access points 4, 4′, 4″, 4′″, 4″″ constitute a mesh network which is highly scalable because the access points 4, 4′, 4″, 4′″, 4″″ are not required to be physically connected directly to the network master unit. The access points 4, 4′, 4″, 4′″, 4″″ can connect directly with other access points 4, 4′, 4″, 4′″, 4″″ within their range, and relay any message, information or status to other access points 4, 4′, 4″, 4′″, 4″″ in such a manner that it eventually is delivered from a hearing device to the network master unit. In addition, it is possible to apply hearing aids that are configured to be used as access points 4, 4′, 4″, 4′″, 4″″ and relay information received (e.g. from another hearing device) to a dedicated access point 4, 4′, 4″, 4′″, 4″″. One of the access points 4, 4′, 4″, 4′″, 4″″ may function as a network master unit configured to communicate with a remote unit. Such a remote unit may be a server allowing external individuals including hearing care professionals to access the remote unit in order to receive data/information from the hearing devices. Such data/information may include the status of a hearing device including the battery level or power level of the hearing device monitored remotely and reported to the remote unit that may be controlled by a service provider. The data/information may include information related to battery change (battery change may be scheduled and carried out by the service provider). Such feature may reduce the “downtime” of a hearing device and the battery lifetime can be extended by remotely controlled power scheduling.

Generally, the hearing aid status and performance may be monitored and problems may be reported to the remote unit and/or the service provider.

The hearing aid status may include the position of the hearing device with respect to the ear canal (so that a wrong positioning of a hearing device can be detected and reported to the remote unit and/or the service provider).

The hearing device status may include the location of the hearing device and thus the location of the hearing device user. In this manner, it is possible to track hearing device users and prevent demented hearing device users from leaving a building. Accordingly, the risk of injury for demented hearing devices can be reduced.

The location of the hearing device and thus the location of the hearing device user may be used to control/regulate the hearing device program being used.

In this manner, it is possible to detect when the hearing device user is in a first location (the dining room) 6 and apply predefined hearing device settings in order to meet the conditions of the first location (the dining room) 6.

In the same manner, the system makes it possible to detect when the hearing device user is in another location and apply predefined hearing device settings in order to meet the conditions of this other location. It is possible to use the time to further fine-tune the settings. In this manner, the system according to the disclosure may apply information about both the location of the hearing device user and the time to provide the most optimum settings.

If the hearing device user is located in the dining room about dinnertime, dinnertime specific settings may be applied. Likewise, the system may be configured to apply predefined hearing device settings dependent on other locations

It is possible to apply various health monitoring features (e.g. heart rate, blood pressure or temperature) which may provide the hearing aid user with a sense of security when wearing the hearing device.

The system according to the disclosure makes it possible for the caretakers/service provider to have access to data from a plurality of users in the same the remote unit (e.g. a server) using only one platform. It is in particular possible for the caretakers/service provider to gain precise knowledge of battery level in all hearing devices.

The data received by the central unit 10 may be accessed through a remote unit (e.g. by a hearing care professional via the Internet 12). Accordingly, the system according to the disclosure provides access to data transmitted by the hearing devices 8, 8′, 8″, 8′″, 8″″, 8′″″ in an easy manner even from a remote location. Therefore, the data transmitted by the hearing devices 8, 8′, 8″, 8′″, 8″″, 8′″″ may be applied to increase the comfort of the hearing device user and to provide a way of determining the correct time of service or replacement of elements such as the battery.

FIG. 4 shows a schematic view of a hearing aid user 20 wearing a hearing aid 8 provided with a sensor, wherein the hearing device 8 is configured to communicate wirelessly directly or indirectly with a central unit 10.

In the bottom part of FIG. 4, a schematic view of a hearing aid user 20 is shown. The hearing aid user 20 is wearing a behind-the-ear (BTE) hearing device 8 behind the ear 18, wherein the speaker 22 has been positioned in the ear canal. The hearing device 8 is equipped with a sensor and a communication unit configured to communicate wirelessly with communication devices 48 in the surroundings of the hearing aid user 20.

In the top part of FIG. 4, a schematic view of a hearing device 8 is shown. The hearing device 8 communicates wirelessly with a smartphone 48 that is communicating wirelessly with a central unit 10 formed as a server 10. An auxiliary device 27 is provided next to the hearing device 8 in FIG. 4. The auxiliary device 27 may communicate wirelessly with the smartphone 48 and the hearing device 8.

The hearing aid 8 may be configured as a health monitoring hearing aid 8 configured to measure the electrical activity of the brain by using electroencephalography (EEG). The hearing device 8 may therefore comprise sensors for detecting EEG signals and a unit for transmitting the detected EEG signals, descriptions of the EEG signals, or decisions based on the EEG signals to the smartphone 48 or another suitable device. The hearing device 8 may comprise sensors configured to detect or estimate one or more of the following parameters: heart rate, heart rate variability, oxygen saturation (level of oxygen), blood pressure and level of sugar in the blood, body temperature, bioelectrical impedance, skin conductance, ultraviolet (UV) exposure, acceleration, vibration, pH, bacteria concentration, blood glucose level. The hearing device 8 may comprise an accelerometer, a pH sensor, a pH sensitive-coating, a blood glucose meter or printed pigments as a chemical sensor for bacteria by way of example. The sensors may be integrated in the ear piece of the hearing device (e.g. a dome or an ear mould).

The smartphone 48 may be replaced by another device capable of providing the required communication. Such devices may include a tablet, PC, and wearable devices as Smartwatches and Smartglasses. The device may contain one or more microphones.

Sensor data received by the central unit 10 can be communicated wirelessly via the Internet 12 by means of a wireless data connection 16. Hereby, the data can be accessed by a hearing care professional from a remote location.

The wireless data connections 14 may be conducted by using any suitable communications protocol, including Bluetooth Low Energy (Bluetooth Smart) and wireless LAN. The wireless data connection 16 (indicated with an arced line) between the central unit 10 and the Internet 12 may be conducted by using any suitable communications protocol, including a wireless local area network (WLAN), WIFI, Bluetooth or other wireless networking technology.

FIG. 5A) illustrates a schematic perspective view of a hearing aid 8 according to an embodiment of the disclosure. The hearing aid 8 comprises an ear piece 30 provided with sensors 24, 26, 28 and a speaker 22. The sensors 24, 26, 28 protrude from the surface of the ear piece 30. The ear piece 30 is connected to the housing 34 of the hearing aid 8 by a tube 32. The hearing aid 8 is a BTE style hearing device 8 with sensors with electrodes 24, 26, 28 formed for example as electrodes.

The hearing aid 8 is a health monitoring hearing aid 8 configured to measure EEG signals, process the EEG signals, or transmit the EEG data to an external receiver like a smartphone for further processing there or in the cloud. The hearing aid 8 may be configured to apply the EEG signals to estimate heart rate and/or heart rate variability.

In one embodiment according to the disclosure, the hearing aid 8 is configured to be a built-in or associated with part of a sports monitoring and training program. The sensor data from the hearing aid 8 may be applied to quantify/estimate the overall mental energy of the wearer at the time of the exercise.

Over time, the hearing aid 8 will provide sensor data including the mental energy after exercise. Accordingly, the hearing aid 8 may be capable of predicting the benefit of a given exercise and optimise the mental energy for the rest of the day by modifying the exercise program.

The hearing aid 8 may be configured to interact with the wearer by playing sounds to signal changes, e.g. saying: go slower, go faster, and increase intensity. Furthermore, the hearing aid may be configured to generate guiding input in form of beeps or other non-speech sounds or via visual indicators on a smartphone.

The hearing aid may be configured to be set into one or more “sports modes” associated to one or more different sound processing schemes. In one embodiment of the disclosure, the hearing aid 8 is configured to detect the heart rate level, preferably based on a detected EEG signal, and apply the detected or estimated heart rate to set the hearing aid 8 in a sport mode. It may be beneficial that the hearing aid 8 is configured to compensate for the distortions of spatial perception imposed by either blocking the ear canal with an ear mould or a hearing aid, and the altered spatial cues due to microphone positions.

In one aspect of the disclosure, the hearing aid is configured to prioritise sound sources approaching the wearer from behind. Moreover, the hearing aid 8 may be configured to prioritise speech sounds with alerting prosody, e.g. an animated watch out.

FIG. 5B) shows a schematic perspective view of another hearing aid 8 according to an embodiment of the disclosure. The hearing aid 8 comprises a built-in sensor integrated in the ear mould of the hearing aid 8. It is possible to apply a built-in sensor in various types of hearing devices including receiver-in-the-ear (RITE), BTE, in-the-ear (ITE), completely-in-canal (CIC) and invisible in the canal (IIC) type hearing devices. The sensor may be a heart-rate sensor configured to continuously monitor the heart rate, analyze, and classify abnormal activity. The hearing device 8 may be configured to inform the hearing device user when it is recommended to consult a doctor.

Abnormal heart rhythm, either fast-fluctuating or continuously elevated, may be a sign of serious heart or circulatory diseases, which in some cases may indicate or lead to ventricular fibrillation (cause of 50% of all cardiac deaths), sudden cardiac death, fainting, or strokes. Prolonged increased heart rate, which may be indicative of cardiovascular risks, such as coronary artery disease (blockage in the pipes of the heart) may be detected by monitoring the heart rate.

The sensor may be optical, mechanical, or acoustical. When applying an optical sensor, the heart rate sensor can be formed as a small light emitter that transmits light towards a blood vessel in the ear canal and a sensor unit configured to measure the reflected light. This approach can also be used to measure/estimate oxygen levels in the blood.

When applying a mechanical sensor, the heart rate sensor can be formed as a sensor unit comprising an accelerometer placed on or close to the surface of the ear mould of the hearing aid 8. The sensor unit may be configured to detect vibration of the blood vessels under the skin of the ear mould. The hearing device may be configured to filter out noise (e.g. from other body movements) by using heart rate measurements conducted by means of the hearing device 8.

When applying an acoustical sensor, a small microphone 38 configured to pick up sound from the arteries surrounding the ear canal may be placed on the side of the ear mould as illustrated in FIG. 5C). Alternatively, vibrations from the blood vessels will excite the air in the ear canal (which makes it is possible to hear the heartbeat when blocking the ears with the fingers). This may be detected by a dedicated microphone 38 provided at the inner side of the ear mould.

The hearing device may preferably be configured to carry out signal processing in order to extract the heartbeat signal from the sensor. It is possible to apply a modulation analysis for this purpose.

The hearing aid 8 shown in FIG. 5B is configured to reduce the occlusion effect. The hearing aid 8 may be provided with a microphone configured to pick up body-transmitted sounds. The hearing aid 8 is provided with a first bore 42 for transmitting sound from the receiver (see FIG. 5C) of the hearing aid 8 towards the ear drum of the hearing aid user. The hearing aid 8 is provided with a second bore 44 for providing ventilation via the vent 40 shown in FIG. 5C.

FIG. 5C illustrates a schematic perspective view of a further hearing aid 8 according to an embodiment of the disclosure. The hearing device 8 is configured to be inserted into the ear canal. The hearing aid 8 comprises a vent 40 for preventing the occlusion effect. The hearing aid 8 is provided with a centrally arranged receiver 22 configured to generate and acoustically transmit sound through an opening in the front end of the hearing aid 8. The hearing device 8 is provided with a microphone connected to a first cross socket 36, whereas the receiver 22 is connected to another cross socket 36.

The hearing devices 8 shown in FIG. 5A, FIG. 5B and FIG. 5C are suitable for being used to track performance during fitness exercise and/or other health monitoring purposes. One main benefit is that the sensor resides in a hearing device already used by a hearing device user.

Detected data is preferably communicated to the Internet/cloud. The data (e.g. EEG-signals) may be used to estimate physical conditions and “mental energy”: Accordingly, the data may be used to generate recommendations such as modifications of user behavior. The hearing device 8 may be configured to communicate with a smartphone.

According to an embodiment of the disclosure, the hearing device is configured to provide one or more acoustic reminders and/or warnings to the hearing aid user 20. A reminder may be generated on the basis on time (triggered by a setting in a personal calendar in a smartphone), location, body measures such as heart rate, temperature, EEG signals and indoor climate parameters such as temperature and humidity. The hearing aid may be used to provide scheduled reminders and also reminders and warnings caused by other events in the daily life. As cognitive skills decline with age, elderly hearing aid users 20 may have an added benefit from such features.

It may be an advantage that the hearing aid 8 is configured to generate a reminder and/or a warning can be triggered by the hearing aid 8 itself and by a smartphone 48 connected to the hearing device 8. The hearing aid 8 may be configured to generate a reminder and/or a warning on the basis of a calendar event in the calendar of the smartphone 48. The hearing aid 8 may be configured to generate a reminder and/or a warning related to medicine intake, wherein the reminder and/or a warning is generated by using a smartphone application that has the prescriptions stored and a Near Field Communication, (NFC) reader or a QR code reader or a bar code reader configured to detect and monitor a pillbox from which the medicine is taken.

The hearing aid 8 may be configured to generate an exercise reminder, triggered by calendar (time) or physical monitoring of the hearing aid user 20 directly from the hearing aid 8.

The hearing aid 8 may be configured to generate a reminder and/or a warning triggered by EEG signals detected by the hearing device 8.

The hearing aid 8 may be configured to detect that the hearing aid user 20 is falling asleep (by means of EEG signals detected by the hearing device 8) while driving a car.

The hearing aid 8 may be configured to detect parameters related to the local climate, e.g. moisture from rain or shower. If possible, this should be triggered before actual water drops hit the hearing aid. The hearing aid 8 may be configured to generate a reminder and/or a warning based on such detected climate related parameters.

The hearing aid 8 may be configured to detect parameters related to the location, e.g. a warning triggered by the location detected by a Global Positioning System (GPS) receiver. The hearing aid 8 may be configured to the distance to water (shoreline). Such warning may be generated in order to remind the user 20 to take the hearing aid 8 off, before going swimming.

Accordingly, the hearing aid 8 may be the centre of relevant acoustic notifications to the user 20. All reminders and/or warnings and/or alarms may preferably be spoken in clear language. The reminders and/or warnings and/or alarms may be postponed up to a defined time limit, if the surroundings are too noisy for a good playback. Likewise, it may be an advantage that a “repeat” feature is provided, in such a manner that if the user misses a reminder and/or warning and/or alarm, said reminder and/or warning and/or alarm should be visible on the smartphone 48.

FIG. 6 illustrates a system for intelligent and wireless monitoring and management of diabetes in hearing devices.

Diabetes results in abnormally high concentrations of glucose in the blood. Therefore, diabetic patients monitor their blood glucose levels in order to control when an antihyperglycemic agent such as insulin is required. Blood glucose monitoring is usually conducted by using an invasive method.

Diabetic patients manage high blood glucose levels with oral or injected antihyperglycemic agents such as insulin. Insulin can be injected manually or by means of an injection pump.

According to one aspect according to the disclosure, the system comprises a hearing aid provided with a wireless chip configured to support non-invasive blood glucose level monitoring. It may be an advantage that the wireless chip is configured to enable ongoing and intelligent diabetes monitoring and management e.g. by communicating with Internet of Things (IoT) devices.

According to an embodiment of the disclosure, the system comprises a hearing aid provided with a blood glucose meter that does not require pricking. Such blood glucose meter may be a biochip configured to measure glucose through non-invasive dermatological patches or in body fluids such as saliva, electrochemical sensors, or mid-infrared light sensors. It is possible to apply a sensor that monitors glucose sugar levels without needing pricking. Such sensor may be implemented in a hearing aid according to the disclosure. It is possible to provide an implementation of a non-invasive dermatological patch on the surface of the ear mould or receiver unit.

Such systems are e.g. described in U.S. Pat. No. 4,207,441 and in U.S. Pat. No. 4,532,930.

In an embodiment, the hearing aid comprises multi-electrode array e.g. in the form of a carrier comprising a multitude of electrodes adapted for being located in the cochlea in proximity of an auditory nerve of the user. The carrier is preferably made of a flexible material to allow proper positioning of the electrodes in the cochlea such that the electrodes may be inserted in cochlea of a recipient. Preferably, the individual electrodes are spatially distributed along the length of the carrier to provide a corresponding spatial distribution along the cochlear nerve in the cochlea when the carrier is inserted in cochlea.

The systems may be configured to communicate suitable management to the end-user with voice prompt via the hearing device.

The systems described with reference to FIG. 6, FIG. 7 and FIG. 8 are configured to allow the user to conduct self-screening and self-diagnosis of diabetes. Diabetes diagnosis is typically done with a glucose tolerance test which can be self-administered.

The data generated by the management and monitoring systems can be used to optimise clinical decisions through machine learning and artificial intelligence (a la IBM's Watson). This optimisation can be carried out at a patient level or at a population level.

FIG. 9A) to 9C) illustrates a health monitoring system using hearing devices with a wireless link. Elderly hearing aid users are typically old people who may experience health issue from day to day or subtle changes over a longer time period. Examples may range from reduced daily water intake causing dehydration to slow-growing tumors in the head. Bilateral hearing aids are in the perfect location for monitoring changes to the head. Accordingly, in these embodiments, a first sensor is arranged in connection with a first hearing device, and a second sensor is arranged in connection with a second hearing device of a user, wherein said first sensor is configured to transmit a signal to set said second sensor and said second sensor is configured to receive a signal from said first sensor. That is, a first hearing aid is arranged on one ear of a user and the second hearing aid is arranged on the second ear of a user, wherein the two hearing aids are able to transmit and receive data from each other.

The hypothesis is that the magnetic/electric conductance in the head varies with the relative water level in the head (short term) or pathologic anatomical changes (long term). This can be measured as the signal strength and signal spectrum on the receiving side at regular intervals. Either inductive near link or electric 2.4 GHz can be used depending on which system is most sensitive to the health parameters of interest. Special radio frequency signals on the state of the art hardware may also be applied for this purpose alone.

FIG. 9A illustrates a schematic view of a hearing device user 20 drinking a soft drink or water 50 in response to a thirst signal generated in a brain tissue 54 of the brain 52.

According to an embodiment of the disclosure, the system comprises one or two hearing devices 8, 8′ configured to measure the “water level” in the brain 52 of the hearing device user 20. The “water level” in the brain 52 of the hearing device user 20 may be measured in several ways. If the water level is below a predefined threshold for the hearing device user 20, a “reminder signal” is generated by at least one of the hearing devices 8, 8′ and sent to the user via e.g. a smartphone 48 or as a direct audio reminder, e.g. a speech message. Accordingly, the user is reminded to drink something as shown in FIG. 9A.

According to an embodiment of the disclosure, the system comprises one or two hearing devices 8, 8′ configured to measure the relative water level and log the measurements at regular intervals in order to store in at least one of the hearing devices 8, 8′. Hereafter, the information can be uploaded to the cloud/Internet 12 for use by e.g. a physician to monitor the wellbeing of the hearing device user 20 as shown in FIG. 9B that illustrates a schematic view of a left and right hearing device 8, 8′ communicating with a smartphone 48 and via the Internet 12.

FIG. 9C illustrates a hearing device user 20 wearing a first hearing device and second hearing device. The first hearing device transmits a signal 56 that is received by the second hearing device as a received signal 58. That is, a first sensor is arranged in connection with a first hearing device, and a second sensor is arranged in connection with a second hearing device of a user, wherein said first sensor is configured to transmit a signal to said second sensor and said second sensor is configured to receive a signal from said first sensor. In this way changes in the signals across the brain can be detected and used for diagnostic purposes.

In FIG. 9C, the right hearing device is acting as transmitter and the left hearing device is acting as receiver. The chemical composition of the brain 52 and the anatomy both affect the signal at the receiving end. Via reference data stored in the hearing devices and logging of key parameters over time, the short-term and long-term deviations can be measured and used to inform the hearing device user 20 and/or a physician, depending on the nature of the problem.

It is possible to measure the radio conductance and estimate the physical state of the brain 52 on the basis of these measurements.

In the event of serious changes, such as a tumour in the brain 52 of a hearing device user 20, even small trends deviating from normal can be detected via logging and sent to the physician who then decides when to call the hearing device user 20 for further investigation. The method is completely non-invasive and does not require additional hardware components, e.g. electrodes in the ear canal. It may be preferred that the hearing device user 20 is never informed directly of this because it may lead to unnecessary concerns.

According to another embodiment of the disclosure, the system comprises one or two hearing devices 8, 8′ provided with a dehydration measuring circuitry. Accordingly, it is possible to provide improved hearing devices 8, 8′.

The hearing devices 8, 8′ already contain a power source, loudspeaker (e.g. to produce alerts) and processing device(s) (DSP, MCU). The dehydration measuring circuitry may be configured to perform the dehydration measurement as a “bodily fluid” measurement conducted by detecting an impedance measurement of the internal and external tissue fluid (giving an “2R-1C” equivalent network) over a frequency range (e.g. 5-100 kHz). A four-electrode measurement may be used for increasing the accuracy; the AC current level may be 40 uA. The degree of dehydration may be detected as a change within the impedance pattern. Such solution is easy to implement since the hearing device is already in direct contact with the skin.

It is possible to apply a hearing device configured to contact a recording device in the form as a smartphone, a computer or another device by which it is possible to alert/inform caregivers. The connection between the hearing device and recording devices can be either wireless or wired.

According to a further embodiment of the disclosure, the system comprises a hearing device 8, 8′ configured to provide an audible warning and/or send an alert to a smartphone that may be configured to warn a caregiver by Short Message Service (SMS) and/or send alerts to a more centralized system (PC or Smart Home/Smart Nursery Home Hub) and/or log the detected data when dehydration is detected.

The dehydration measurement function can be either a part of a hearing device or used by a non-hearing device user. For non-hearing device users, a caregiver can hand out a device and setup the measurement parameters and/or alarms.

FIG. 10 illustrates a first hearing device user 20 (a baby) and a second hearing device user 20′ (a child). The hearing device users 20, 20′ are using wearable health monitoring hearing devices 8, 8′ according to one aspect of the disclosure.

Many health conditions go undetected and untreated, with consequences ranging from minimal to death. For example, body temperature; pulse, blood pressure, and level of oxygen and sugar in blood; skin conductance; UV exposure; sudden acceleration, and dermatologic health could be better monitored, and therefore abnormal levels could be addressed.

Fever is a very prevalent clinical sign where body temperature increases above 38° C. Especially in children, fever is an important clinical sign with potentially severe consequences if undetected and untreated.

Pulse (tactile arterial palpation of the heartbeat), arterial blood pressure (pressure exerted by circulating blood upon the walls of blood vessels), level of oxygen in blood (arterial oxygen saturation of functional hemoglobin) or level of sugar in blood (glucose levels: hyperglycemia from diabetes mellitus or hypoglycaemia) are four vital signs that can inform about a person's health status.

Skin conductance (galvanic skin response) is the electrical conductance of the skin: it increases when the amount of sweat on the skin increases. Sweat is controlled by the sympathetic nervous system, so skin conductance is an indicator of psychological or physiological arousal and of stress.

Ultraviolet (UV) light through sun exposure affects human health: UVB radiation induces production of vitamin D in the skin. However, overexposure to UVB radiation causes some forms of skin cancer.

Sudden acceleration can be a sign of a fall, for example in the elderly or in people prone to seizures.

Dermatologic conditions at the level of the outer ear and ear canal such as otitis externa (external otitis or swimmer's ear), dermatitis (eczema), and psoriasis are common. Otitis externa has a prevalence of more than 1% over a 12-month period in the UK1. Otalgia (ear pain), otorrhea (ear discharge), and swelling are uncomfortable and can interfere with hearing aid use, for example by causing hearing aid feedback. The mechanisms of these conditions are varied (no infection, bacterial infection, or fungal infection).

Monitoring is possible and there is a general trend towards self-monitoring of health status and wearable technology. For example, a national telephone survey conducted by the Pew Research Center's Internet & American Life Project found that 69% of U.S. adults keep track of at least one health indicator such as weight, diet, exercise routine, or symptom. However, monitoring is often done only on-demand (not continuous) and from different sensors built in different devices. It would be relevant to collect self-monitoring sensors into one device worn continuously.

In one aspect of the disclosure, one or more parameters are detected by one or more sensors. Hereby, it is possible to monitor physiological states and detect abnormal states through hearing devices and other devices worn at the ear 18 of a hearing device user 20, 20′. Hearing devises may include hearing aids, cochlear implant speech processors and headphones (used with mobile devices).

As hearing devices are worn at the ear level for many hours daily (or worn continuously, for example with deeply inserted hearing aids), they allow for online monitoring. Monitoring of the parameters mentioned above could be obtained in several ways.

In one aspect of the disclosure, a thermometer is integrated to the hearing device. The thermometer may be similar to the infrared ear thermometers currently available on the market. Alternatively, a thermosensitive coating that changes colour according to temperature could be used along with a) a system where the wearer or another person can take a picture of the coating colour with a mobile device for automated diagnosis or b) a “legend” of which colours are indicative of fever, for manual comparison by the wearer or another person.

In another aspect of the disclosure, a pulse and blood pressure sensor (sphygmomanometer) and/or an oxygen in blood sensor (pulse oximeter or functional near-infrared spectroscopy) and/or a sugar in blood sensor (with or without using pricking) is integrated into hearing device 8, 8′.

According to a further aspect of the disclosure, the hearing device 8, 8′ is provided with an integrated heart rate sensor comprising an additional hearing aid microphone in the ear canal or near the vent entrance and monitoring the compliance of the middle ear using conventional 226 Hz compliance measurement. Given the artery running close to the tympanic membrane, the microphone can record the beating frequency (pulse) as changes in the middle ear compliance.

According to an even further aspect of the disclosure, the hearing device 8, 8′ is provided with an integrated heart rate sensor comprising ultra-sensitive mechanical sensors configured to detect pulse on body parts.

Monitoring heart rate in a hearing aid can also be used as an input to a health and fitness application on a mobile device 48, 48′.

According to an even further embodiment of the disclosure, the hearing device 8, 8′ is provided with an integrated sugar level sensor configured to detect the sugar level in the blood by means of an electrochemical sensor, shaped as a biochip that measures sugar by means of a mid-infrared light sensor.

According to another embodiment of the disclosure, the hearing device 8, 8′ is provided with a galvanic skin response sensor integrated into the hearing device 8, 8′.

According to a further embodiment of the disclosure, the hearing device 8, 8′ comprises a UV exposure sensor integrated into the hearing device 8, 8′.

Hereby, it would be possible for parents to determine when to provide vitamin D supplements to their children or when to reapply sunscreen during sun exposure.

According to a further aspect of the disclosure, the hearing device 8, 8′ comprises an accelerometer integrated into the hearing device 8, 8′.

According to an even further aspect of the disclosure, the hearing device 8, 8′ comprises a pH sensor/pH sensitive-coating/printed pigments as a chemical sensor for bacteria integrated into the hearing device 8, 8′.

Monitoring could have a range of applications, for example for screening or diagnosis of health conditions or for monitoring of health status. For example, a person who is under post-operative care could be discharged from the hospital earlier if wearing a monitoring device connected to the hospital that could monitor e.g. changes in blood pressure or pulse. Monitoring of the parameters mentioned in the section above could either be always active (“online” or “continuous”) or only active on demand. On demand could be controlled by the wearer, by another person, or through automatised means, either directly on the hearing aid or other device worn at the ear level or at a distance (e.g., requested by the parent through a mobile device 48, 48′ application for a toddler in day-care, with the option to ‘export’ the controlling and monitoring possibilities for a given period of time to another mobile device 48, 48′ such as the grandparents' mobile device 48, 48′).

Most applications would be digital, but some low-cost applications could be analogue (e.g., printed pigments as a chemical sensor for bacteria). For all applications, an automated system could store levels for display of trends over time (“self-monitoring”), with the option to send the information to third parties such as health professionals 46, electronic health records, or social media. The automated system should also be able to detect levels outside the normal range (normal range level should be individualised, e.g. abnormal body temperature should be age-dependent). Detection of abnormal levels should trigger automated actions which would be specified by the wearer 8, 8′ or by another person.

The hearing devices 8, 8′ may be configured to detect pulse and blood pressure levels and inform a health professional 46 via a smartphone 48, 48′ in case that the detected levels are within a predefined critical range.

The hearing devices 8, 8′ may be configured to detect an abnormal stress level in difficult listening environments triggered by an increased digital signal processing activity in a hearing device 8, 8′.

The hearing devices 8, 8′ may be configured to detect the sugar levels and inform a health professional 46 via a smartphone 48, 48′ in case that the detected levels are within a predefined critical range. The hearing device user may be informed that an insulin dose is required.

A parent to a child 20, 20′ wearing a hearing device 8, 8′ may call a health professional 46 to find out if medication is required in case the child 20, 20′ is sick. Since the hearing device 8, 8′ is provided with a sensor (not shown), the hearing device 8, 8′ is capable of conducting a measurement, e.g. of the body temperature of the child 20, 20′. Accordingly, the hearing device 8, 8′ detects the body temperature of the child 20, 20′ and sends the information to a health professional 46. The information may be sent via wireless data connections 14, 16, 16′ and the Internet 12 by using a sending smartphone 48 and a receiving smartphone 48′ as indicated in FIG. 10.

The temperature measurement may be conducted automatically on a regular basis (such as once every quarter of an hour or every hour) or on demand.

The hearing device 8, 8′ may be configured to receive an “instruction” to conduct a measurement initiated by the health professional 46 by means of his smartphone 48′. The smartphone 48′ of the health professional 46 may e.g. display a text indicating the temperature, resting heart rate of the hearing device user 20, 20′. Accordingly, the health professional 46 is capable of remotely treating the hearing device user 20, 20′ on the basis of the measurements taken by the hearing devices 8, 8′.

The smartphones 48, 48′ may be replaces by other electronic devices (e.g. a computer or a tablet) comprising a suitable communication unit.

In an aspect, the functions may be stored on or encoded as one or more instructions or code on a tangible computer-readable medium. The computer readable medium includes computer storage media adapted to store a computer program comprising program codes, which when running on a processing system causes the data processing system to perform at least some (such as a majority or all) of the steps of the method described above, in the and in the claims.

By way of example, and not limitation, such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. Disk and disc, as used herein, includes compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray disc where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above should also be included within the scope of computer-readable media. In addition to being stored on a tangible medium, the computer program can also be transmitted via a transmission medium such as a wired or wireless link or a network, e.g. the Internet, and loaded into a data processing system for being executed at a location different from that of the tangible medium.
